“I’m surprised the camera caught them at that speed. It’s an astonishing figure,” he said. “I go up there fairly regularly and most people behave themselves. It’s amazing you can get up to a ton on that bit of road but I suppose you could if you boot it.”

Other speeders on the county’s roads included a motorist on the A47 who was caught doing 70mph more than the speed limit, one of the biggest excesses on the county’s roads during the 2016/17 period.

Simon Hackett, 45, of Arles Avenue in Wisbech, was caught riding his Honda CBR 1000 motorbike at 142mph on the A47 – which has a 70mph limit – at Terrington St John in August last year. He was handed a 60-day driving ban, fined £250, ordered to pay £85 costs and a £30 victim surcharge after admitting the offence.

The figures, obtained under a Freedom of Information request, revealed that the Terrington St John stretch of road was where the most 100mph speeders were recorded, with 30 caught by speed cameras.

The A11 at Wymondham and Besthorpe also saw a high number of 100mph or more speeders, with 28 caught during the period.

They included the rider of a Suzuki motorbike, who was captured doing 126mph and the driver of an Audi S4 doing 121mph.

Of the 180 motorists recorded by Norfolk Constabulary, 132 have been prosecuted, with 29 cases ongoing and 19 cancelled.

Inspector Jon Chapman, from the Norfolk and Suffolk Roads Policing and Firearms Operations Unit, said: “Speeding is recognised as one of the ‘fatal four’ offences which leads to people being killed or seriously injured in a collision along with drink driving, using a mobile phone and not wearing a seatbelt.

“The higher your speed, the less time you have to react. Think... Could you stop in time if something unexpected happened in front of you?”

In Suffolk, the highest recorded speed was 154mph on the A11 on at Icklingham, the highest speed ever recorded in the county and one of the highest in the country last year.

Louie Howlett, 21, of Lakenheath High Street, was the man behind the wheel and was banned from driving for 56 days after admitting the offence. He was also handed a £250 fine.
